Promoting Server 2008 Std to Server 2008 r2 as DC

We have bought a new server where so far i have migrated the data and joined the new server (2008 R2) as an additional DC but still the operational master is Server 2008 Standard Edition. Now with the help of adprep /forestprep i was able to join the new server successfully and currently want to demote the old one by CAREFULLY transferring all the roles required without screwing up anything. I want AD and GP work as usual without any downtimes. I forgot the powershell commands or if there is a GUI way to do it. It would be great. I know the way but i don't want to take any kind of risk because i can't recreate the domain for 60 computers again. Thank you.

To transfer roles go through this link http://www.petri.co.il/transferring_fsmo_roles.htm

Before transferring run Dcdiag on both servers to check health of the domain before moving and demoting server.

Nice job bringing the new box online.  How many total DCs do you have on the network right now?

Some other things to look for, if DNS was installed on the old DC make sure the new box has DNS and also make sure clients (static and DHCP) are pointing to the new box for DNS.

Thanks

The ip address of the old one is 192.168.1.100 and i am using that as DNS in the new server right now and currently all the users network drives and applications are hosting with the "server name" so there is no issue so far, but i want to disconnect the old server without messing up with the new one. I went through that link already infact i did this couple of times but the place i am right now is a sensitive case and i can't make any DOWNTIMES here no matter what. I only need an experts advice to do the STEP BY STEP procedure to get rid of the old server and bringing up the new server.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

right now how many total DCs are there on the network?

Just one

ok in that case and since downtime is unacceptable I would keep both up.  Think of the worst case (and it happens)  You run with one DC and that has a hardware or other issues.  You are really in trouble then and there will be downtime.  Have at least two DCs and there should not be downtime.

Thanks

I have only one DC as a main server and thats it

Mike KlineCommented:
you should at least have two because of the reasons I outlined if downtime is a big worry.  If not and you have transferred the roles and are willing to take the risk then you can use dcpromo to demote the old one...I would not recommend that.

I would have to agree with Mike two DCs should be the norm in any environment

I have done it once where i joined one dc and demote the old one and it worked fine and it is still working fine but that does not have any group policies applied on Domain users but this network environment is quite big in numbers and requires a precaution while migrating the data and disconnecting the old server. What i am thinking right now is to transfer the FSMO roles and try tomorrow night by switching of the old server if it really works out or is it must to DEMOTE the old server >?

Don't demote the old server this is not required. Make sure you run dcdiag to check the health of your domain before moving fsmo roles

Above are the two prompts i am recieving during the DEMOTE of the old server. So far i have transferred all the FMSO roles required to ADC and made it as a PDC. Just want to clear doubts on this two prompts specially the second one if i should keep it checked or uncheck and go further ?

Those are normal.

Make sure your DC is a Global Catalog.
